Is it possible to determine the beginning of pregnancy for the ovulation test?
To determine the time of release of a mature egg from the follicle, use a substance that reacts to the presence of residues in the urine of a luteinizing hormone woman . In the body, its maximum concentration is noted directly with ovulation. As a rule, this process lasts about 24 hours. The probability of successful fertilization of the female sex cell with spermatozoa is very high in this period. The ovulation test at this time shows 2 strips.
The fact of the onset of pregnancy is established using a test that reacts to the appearance in the urine of the chorionic gonadotropin, a hormone produced after fertilization.
Considering that 2 of these tests, which require the same procedure, contain different reagents, you can not use the ovulation test to determine pregnancy and, conversely, the determining pregnancy, to determine the date of ovulation.
What is the result of the test for ovulation during pregnancy?
Sometimes a woman decides to hold it during a delay or at an early gestation period. As a rule, in this case it displays 2 strips. A positive test for ovulation is almost always observed during pregnancy, but it does not show the very fact of the onset of gestation.
Such a result is not reliable. The thing is that hCG and LH are very similar in chemical structure. It should also be taken into account that the sensitivity of tests for determining ovulation is higher, which is why it can erroneously react to the increase in hCG level that occurs after conception.
A negative test for ovulation during pregnancy is a direct proof that the level of LH at this time is reduced, as it should be normal. Use this device at this time you can, but still the final conclusion is made on the basis of a pregnancy test.
